| 摘 要： | 在建的福建省龙岩市红坊互通立交建设区域属于岩溶极为发育地区，桥梁桩基沉降量计算的准确度直接影响到该工程的安全性和经济性。采用FLAC3D有限差分软件进行数值模拟分析，得到6种桩径的桩基位移情况。经过与其它3种用设计规范计算得到的数值比较，发现用有限元数值模拟的结果与按《建筑桩基规范》计算的结果很接近，并对其进行原因分析。

| Abstract: | The Hongfang (an area in Longyan, Fujian) interlinked flyover under construction is located in an area with extremely developed karst. The accuracy of settlement calculation of the bridge pile foundation directly affects the safety and economical efficiency of the project. The displacements of piles with six different diameters were obtained by means of numerical simulation analysis with the finite difference software FLAC3D. After comparison with the numerical values obtained through calculation according to three design codes, it was found that the results of finite element numerical simulation were very close to those obtained through calculation according to Technical Code for Building Pile Foundation, and the reason was analyzed. |
